Fig. 5 is a detail sectional View taken on the line 5--5 et ig. d.

The Stand portion of my machine ie niade np et e nnnfiher of hox-lile unite of sheet inetal,-Snitohli7 secured togetl'ier. Asn upper large compartment has the hottoni, 10, o'f' sheet nietal, the sides, l1, and ende, lient npirardl;7 therefrom. The top, 13, is made of a Sheet of motel, havingrthe downwardly drawn annular flange, lil, which recei the ripper edges ot the sides ond ende, ll. and 1.52, respectively, andie enitahly .Le cured thereto hy Soldering, riretinp; or fipot ne ling. i

In orderto Vgire a finished appearance to the ina"h.ine the cornereformed hy the junctnre of the eidee, ll, and ends, l2, `are rounded olf, ae shown in l, ond legge, lo, serve to secure the adjaeentedges to gether andto support therreinainder of the compartments, l

The opper compartment may he enhdivded by o transverse partition, `as indi cated in dotted lines at `16 in Fig. 4C, so as to i provide the eprice, A., in which thexpopped lll) corn receptacle is situated, and the space, B, into which the lower portion of the kettle projects.

The top, 13, above the space, A, is provided with a rectangular opening, bordered by the depressed flanges, 17 (see Figs. 1, 2 and 3).

The popped corn receptacle, 18, is of rectangular torni to fit within the opening just mentioned, and is provided at its upper edge with outwardly-projacting dangcs, 19, which rest upon the depressed flanges, 17, the upper surfaces thereof being sligntly below the level oi the top, 13.

v Secured to brackets, Q1, in the bottoni ot the receptacle, 18, are a number o1c longitudinally extending parallel bars, Q2, which form a false bottone or grate, upon which the popped corn will rest, and through which the unpopped kernels will fall. ln scooping corn troni the receptacle the scoop is lnoved longitudinally ot the bars, 22, and the ernels will be scooped up without catching against any transversely-extending inenibers, as would be the case were rneshing to be used instead ot the parallel bars. Thus there is no likelihood ot the crnels being crushed.

Adjacent one side of the receptacle opening, just described, is a circular opening bordered by an upstanding tlange, Q3, drawn from the metal of the top, 13.

The kettle comprises two elements; a semispherical kettle proper, 2li, and an integral apron, 25, extending drnvnwardlj.7 troni the upper edge of the bowl, spaced somewhat therefrom and ,reterably flaring outwardiy slightly, as shown in the drawings.

The kettle is spun 'from a sheet or aluininuni or copper, and the lower edge of the apron is beaded, as at 26, to give strength, which may be increased by the additional rein-forcing rod, 27.

The lower edge of the apron is designed to encircle the flange, 93. In order that the heated gases may escape, openings, 25a, are provided in the apron, 25.

In :forming the juncture between the kettle proper, S24, and the apron, 25, a depressed shoulder, 28, is provided which leave a: opstanding encircling shoulder, 29.

The kettle is hinged to the top, 13, by means of a hinge, 30, secured thereto and scoured to the apron, in a. position centered between the extremities oi the top, 13.

At a point diametrically opposed to the side hinge, 30, a handle bracket, 31, is secured to the apron, 25.V The bracket, 3l, carries the handle, 3:2, and is provided with a pair ots aced ears, 33, receiving a lug, 3&1-, tasteneil to the cover, 35, and forming vtherewith a hinge.-

The cover,.3,5, is in the toi-nieta sei'ni Vsphere with" av flattened portion, 'as at` 36 recense (see Fig. 4), and is spun of the saine inetal as the kettle. The lower edge of the cover, 35, is beaded and provided with a reinforcing band, 37, the mouth ot the cover being ot such diameter that the bead will rest against the shoulder, 52S, and within the shoulder, Q9.

The shoulder, 29, is inclined inwardly a little so that as the cover is lowered to rep;- .ister with the kettle the shoulder, 2S), will serve to guide it into accurate position whereby the stirring linger, which will later be described, will be brought into close engagement with the interior et the kettle.

rlhis is important inasmuch as a single hinge, in which a sinall aniount of' lateral play is allowed, is used.

Directly above the hinge. 30, a keeper, 3S, secured to the apron, 25, an,L is curved outwardlf.v at its upper end to provide a hook, 39. fr latch, Ll0. is provided which has a curved linger, d1, adapted to entend into the hook, 39, and engage the inner surface thereof, and is linked to the cover, 35. by means ot a link, Lil-2, hinged at #13, to the latch, Ll0, and at di, to a bracket, 45, sccurcd to the cover. rl`he latch, Al-(l. has a curved shoulder, 4:5, adapted to engage the apron, after the end oi' the linger, Ll1, has nic-ved upwardly into the hook. 3f), bcyond the center line (indicated at el?) connecting the two hinge pivots, 13 and ell.

The end of the latch, 40. thence extended outwardly and provided with a handle, 4S.

The parts are so arranged that in order to move the linger, l-l, downwardly toward nnlatcbed position `troni the position showrin Fig. 2, the linger, 111. inust increase its pressure against the hook, 39. and thus to spread the pivots, 43 and del, further apart. Thus the resiliency7 oit the parts, aided by the weight of the handle, 4S, will ell'cctivelv serve to maintain the latch in locked position.

ln einptv r the corn from the kettle the handle, 1;. raspefl by the lett hand ol' 'the operator and the kettle tipped upwardlabout the hinge, 30. to the position shop n in dotted lines at l) in Fifi'. 1. hliniultzr the operator ,'jrasps the handle. Al-f. the rieht ha*- l w. and swine@ it on iarther in the .saine direcunlatches the rover tion, thereinv allowing j[he corn to pcrpendicnlarlv troni lnitwcen the tvo halves of thc kettle.

The spherical c `-ntonr of the kettle proper allows the corn slide tree/lj.- th rc'rroin when in the position shown, and l find that the nionientnin or the sliding kernels will ca' the kettle 'to be cleared ot all ol the cora so that no kernels remain. Thus the dunipinc operation is Quickly effected. and upon s p ngiin the kettle back to its ori ial positionthe cover inav be 'simply allowed lll) to drop by gravity, the momentum oil the swinging handle serving to overcome the resistance oit the hook, 39, to the latcliing linger, ll, when the latehing is being.;1 etlected. i

Mounted in a bracket, 4:9, secured to the flattened top, 36, of the cover, and entend ing through said top to a point near the bottom of the kettle is a stirrer shaft, o0, to the lower end of which is secured a sinele stirrer, 5l, which. is preferably Welded to the shaft and is curved to lit the contour ot the kettle.

in ordinary drire mechanism coniprii a shaft, 52, journaled in the bracket, provided at its onter end wi th a gear han 53, and at its inner end with a crown ,f gear, 5l, and a bevel pinion, 555, Secured to the shaft, 50, and nieshed `with the crown gear, 5d.

lt Will nonT been seen that as the cover is sirnnp; away troni the center, the stirring; 4tlnger, 5l, Will swing on an are which is approximately coincidental with the are ol the kettle, 24:, yalthough having; a slightly larger radius.

As a result, the linger, 5l, Will swing: clear ot the kettle when the cover is litted, Without binding.

When the kettle is not in nee, it is raised to the position shown in dotted lines in Fig. 2, thus preventing scorching. A bracket, 32, hinged at 32h, supports the kettle in this position.

A bracket, 56, limits the tipping inovenient-vol' the kettle to the position sho-Wn in dotted lines in Fits?.

Beyond the kettle the top, 13, is apertnred and flanged, as at 5T, in a manner similar to the construction described tor the popped corn receptacle, to receife a Warming` pan, 58.

it.. cover, .59, is provided for the pan, 5S. A partition, G0, entends 'ans-sters ly ot the upper compartment, is secured to the sides, ll, and enclos s, topjeth-ir with the pan, 58, a space next to the end wall, l2, in which the gasoline tank, (il, is secured by n'leans oit brackets, G2.

Supported on a bracket, 63, helena7 the kettle, 24e, ie a burner, Which may he supplied with fuel 'li-oni the tank, Gl, by means of a hollow wire connection, (35. The parts described iorin no part oit my present invention and therefore have not been illustrated in detail.

The heated frases rising troni the burner, Gal, Will strike the bottoni et the kettle, near its center, and will spread outwardly on all sides thereof' until the upper limit of space between the kettle and apron. is reached.. rlllhence the only avenue ot escape for the gases is through the openineis, 25, in theapron. 25and the cooline eases lthe openings in the tace of the apron by the ascending' cnrrent ot hotter troni tl e burner.

Since it is necessary tor the heated ,eases to pursue a downward course in escapingF rioni the machine, it will be seen tha:r it Will not be necessary to allow as large a volume fr# small llame 'troni the burner, act-ing VL ,.ectly an'ainst the bottom ot' the kettle,

will maintain the lower portion et' he kettle at practically the same temperature as the upper portion, which is constantly fl rounded with an envelope oit heated ,in

By thus subjlcting; a large surface oi the kettle to the action olA the heated gases, the

air within the kettle is quickly brought to the proper temporatore tor popping', and the bursting' oit the kernels is more completely accoinp hed by the heating et the air with in lne ki 'lle than is the case Where the bottoni et the kettle is subjected to a ninch hi @hier temperature than the remainder. As a result, a more unitorin popping,l is obtained., tower unpopped kernels are lett in the kettle and the danger ot scorching is minimized..

A shelf, 66, ot sheet metal. having a drawn flange, Gi", is secured to the legs, l5, and supports at one end ot the machine an enclosed sheet metal box, 68, in which is secured an auxiliary burner, 69, similar in construction to the burner, 64, and supplied from the tank, 6l. by means ot a hollow Wire, 70. A. door, 7l, in the end Wall ot the box, 67, allows access to the burner.

The burner, 69, may be used to Warm the receptacle, lil, and when the machine is used as a camp stove the receptacle, 18, serves the purpose ot an oven.

To this end l provide means tor covering the compartment, 18, which l will now doscribe.

A cover plate oit sheet metal, 72, has its side edges rolled around reds, T3, as at 7l. The rolled edges, 7l, are slide-bly receii cd under brackets, 75, secured to the sides ot the machine, as illustrated in Fig. 5. The rods, 73, are bent upon themselves to provide parallel portions, 76, which are slidably mounted in bushings, 7"?. secured to the end Walls, 12, vertically below the brackets, 75.

The space lbetween the side walls oit the receptacle, 18, and the sides, ll, ot the upper compartment is auflicient to allow the inward Will therefore be forced downwardly tlnengilgslidng ot the portions, 76, et the rode, 73.,

when the cover member, 72, is slid to the dotted line position shown in Fig. 4l.

lli'hen in closed position the end edge ot the cover, 72, is received under a pair oi keepers, T8, secured to the top, 13, as illustrated in Fig. 3. The cover, 7 2, when in the extended position shown in Fig. 4lin full lines, serves as a shelf to support sacks of popcorn, and ar rack, 79, is secured thereto to maintain the sacks in upright position.

An auxiliary container, 80, is secured to the other end wall, l2, of the upper compartment, and is normally closed by a. cover, 8l, hinged at 82, to the outer edge thereof. A rack, 83, is secured to the cover, 81, in such position as to form a brace to maintain the cover in inverted horizontal position, as illustrated in dotted lines in Fig. 4f, when the cover is swung back on the container. then in this position the cover serves as an additional shelf. The compartment, 80, may be used tor storing sacks of peanuts and the like.

Somev changes may be made in the eonstruction and arrangement oi the parts ot my invention Without departingfrom the real spirit and purpose ot my invention, and it is my intention to cover by my claims any modified forms of structure or use et mechanical equivalents, which may be rea` sonably included Within their scope.
